Por 15 Options

What would be the best combo to use on the floor pans, once the floor tar is off? I have solid pans, so only anticipating surface rust.

For the center tunnel, or can/should the tunnel be taken off to remove the rust?

Just to give more detail on my experience:

1. Used a POR 15 floor pan repair kit several years ago on a different car (not a teener). I guess it worked well and did what the product said it would, but now that I can weld (at least a little), using fiberglass patching seems like such a hack. It did fine where there was still solid metal.

2. Used it on my teener's fuel tank that had been sitting for over 10 years with fuel turning to tar (or back into dinosaur) and I thought it turned out great.

3. Used it to redo my teener's floor pan, and this turned out better than the first try because by this time I fully cut badly rusted areas away and welded in patches. Again, I'm still learning to weld, but I believe the repair is solid, if not pretty. I did a pretty thorough job cleaning everything up and prepping:
After (don't have a good before pic):


4. Used it on my second teener's fuel tank similar to the first time, and it did not turn out as well. I think I must have rushed the prep job (the cleaning and metal prep) as the POR15 coating didn't seem to stick as well. That's another lesson: when using it, really plan your day around it, as you don't want to rush the process.

Again, when used correctly with thorough preparation I think it works well. Don't use it to replace metal or "convert rust" but to prevent additional corrosion on otherwise structurally sound metal.

As for the tunnel, that's a tough one. I've read threads here about how to get in there, and unless you cut into it from above or through floor pans I think you're stuck trying one of those creative solutions (like mentioned above) that will help but may not fully treat/encapsulate everything. I may look into that Eastwood solution that was mentioned here a couple of days ago, as my tunnel also has the surface inside that annoys me (IMG:style_emoticons/default/hissyfit.gif)
